Newd Delhi, Aug 11: NLCILThermalUnitsandMinesarecertifiedforEnvironmentalManagementSystemISO:14001, complying to the environmental stipulations. NLCIL is equipped with the requiredEffluentTreatmentPlantsandisensuringitscontinuousoperationtomeetthestandardsprescribed by Central Pollution Control Board (CPCB), Ministry of Environment, Forest andClimate Change (MoEF& CC), Tamil Nadu Pollution Control Board (TNPCB). The quality oftreated effluent is being regularly monitored by TNPCB, latest being done on 30.06.2023, inwhichparametersarewithinthepermissiblelimits.Inaddition,3^rdpartyanalysisofwatersamples is also being carried out, as per the Environment Clearances (EC) conditions stipulatedand the same are being submitted to TNPCB &MoEF CC. All the effluent parameters are withinthepermissible limits.

NLCIL has been taking the following measures to keep in check the fugitive dust emissions fromits industrial activities as a part of creating an ambient atmosphere & to provide a good healthierenvironment:
1. InstallationofWatersprinkler/Fogsystems
  1. Haulroadwatersprinklers
  1. Vehicular water spraying/Pressurized mobile water sprinkling system forroadsinsidethemines
  1. Conveyorwaterspraying
  1. Workingface waterspraypipelines
  1. FixedwatersprinklersgunsinBunkerarea
  1. FogCannondustsuppressionsysteminCoalStockYard
1. Practiceof WetDrilling
1. AdoptionofElectricallyOperatedBeltConveyorSystem&BucketWheelExcavators (BWE) for the past 3 decades to the maximum extent to reduce pollutionload&carbon foot print.
1. NLCIL has also installed CFBC boilers in place of PF (Pulverised Fuel burning) forNLCIL’s new and expansion Thermal Power Plants at Neyveli and it is a remarkablebreak through for further minimizing the emission of CO2, SO2, NOX which havehigher thermal efficiencyand loweremission
1. Dust suppression by green belt development in Bunker Areas & around the miningarea.

In this regard, Neyveli is also declared as a “Green Zone” by Central ElectricityAuthority(CEA)

3tier Green belt development

Continuously operating Air Pollution Control (APC) measures such as AgglomeratedDust suppression system (ADSS), water jets, Water sprinkler systems etc to controlthefugitiveemissions.
- Electrostatic Precipitators (ESPs) of more than 99% efficiency have been installed &continuously operated in all the power stations of NLCIL to remove the ash particlesfromtheoutgoingflue gas.
- In addition, the implementation of Flue Gas Desulfurisation (FGD) is under progresstocomply withtheMoEF&CC’srevised emission norms.
NLCIL is also utilizing 100% fly ash generated by supplying to Brick Manufacturing Companies,Cement Manufacturing Companies, etc., complying with the guidelines of MoEF& CC, Fly AshGazetteNotifications issued fromtimetotime.
NLCILcompliestoall thestipulationsbrought outbyMoEF&CC/CPCB/TNPCB.

NLCILiscontinuously undertaking allthenecessaryEnvironmentalProtection measures toensure air andwater quality parameters at ambient level,which arewellwithin thepermissiblelimitand it isknown forcarrying outIndustrial activitiesalong with sustainable environmentalactivitiessinceits inception.
